From “Molecular Disruptors” by Molectech Research LLC GmbH

Molecular disruptors work by interfering with the bonds that hold matter together–hence the name. By disrupting these bonds, the material in question can be pulverized into smaller molecules or even its component elements. As many of the by-products from this process are toxic, areas that have sustained heavy disruptor fire tend to be hazardous for days, weeks, even years after combat has ended. The toxic by-products also increase mortality among those who survive the terrible injuries wrought by the molecular disruptors, as well; even a glancing wound or total miss can produce free elements like chlorine gas.

For this reason, molecular disruptors are completely banned by treaty. Unfortunately, the same principles behind their operation are widely used in power cells, ovens, and other day to day technologies, meaning that it is relatively easy to convert them into crude but effective disruptors. This makes them extremely popular with criminals, terrorists, and black-market mercenaries, who often use the weapons against police and military that are armed with less effective but treaty-permitted ordnance.
